known that I, FORD MARsELLIs, a

To all Be i citizen'I `df the/United States, residing at Berkeley, in the county of Alameda and,

State 4of"` California, have invented certain new andi, useful Improvements in Railroada sim le,".compact, serviceable and practicalv porta le drilling-machine which will drill one" or more holes at a time in-railroad rails im.

` ,other, eitlrer by situ, for vthe purpose of connecting electrical bdnd-wires, or for any purpose; and which can` be readily moved from one point to anforward pait being broken away. Fig. 1a is. part, on a reducedA a plan of .said forward scale. Fig.` 2 isla right side elevation of the the drill-frame, rolien at one end.' Fig. 5 is a sectional det ilon line of Flg. 4,

machine. Fig. 3. is a rear end f" elevation. Fig. 4 is a plan view ofthe bottom chords of showing also the parts immediately above.

Fig. 6 is a diagrammatic side elevation, showmg in full lines ,the rear of the machine ele-g vated, to adapt it fortra'vel-ing, and showing the normaliA working osition in dotted lines.

The main frame o the machine includes a ri ht sill 1 with handles at its ends anda left sil 2, with end handles, said sills being adjustably supported by truck members comprising a front axle 3, arear axle. 4 having a sleeve 5, and Wheels', the wholebeingsuitably assembled to 'form a portable *frame to travel on tra" k rails 52.

The terms right, left, front 4and`rear are herein applied from the'standpoint of a person viewing the rear end elevation, Fig.- 3.

The drill-frame is composed of the pair of tie-bars `7; the depending uprights 8, bolted to the tie-bars at each end; and the pairyof bottom chords 9 secured tothe lower ends of the uprights` 8 hand, or by motive power" a lift-rod-22, Fig. 3,

, said drill-frame being.`` propperly'stiiened, as, for example, by the diagonal braces 5 3, shown in Flg. 3,' connecting tl-iaiiebarsand vbottom chords and by the braces 54, Figs. 2 and 3, connec ing the bottom chords to the main-frameI sills.

The drillframe is 'carried by .the main-n.

frame by its tie-bars. 7 bein bolted to the sills of said main-frame, and y 'the' braces 54 boltedv to saidsi'lls and said drill-frame;

when down in operativeposition, is supported ontlie track-rails 52, byhaving its bottoni chords 9 rest directly upon said rails, with their extremitiesg bent over the rail tops,

to embrace them as shown in Fig. 3.

pins/13 and 14, form, in the present illustration, a systemof feed-links for operating onf four drill-spindles, through theaction of one .lever 10. f l

15 are the two'drill-lspindlds of the left', and 16 are the two drill-spindles of the right side.

Fig. 5. The former, at their inner ends, have a thrust-bearing-17, and the latter have a corresponding thrust -bearing 18. The thrust-bearing 17 has apair of iaws 19, to

,which the outer ends of theA left feedlinks 12 are pivoted by pins 13; and the thrust-bear'- ing 18 has a similar pair of jaws 20 toy which the outer ends of the right feed-links 12 are pivoted bv pins 13.

"The.d1illspindles 15 and 16 are supported by and revolve in housings 21, which arelse-K cured to the drill-frame bottom chordsjQ.

The pins 14 which connect the adj ac'ent er'ilsr of the members of the left, and right feed-1 links 12 extend across to thecbmpanion feedllink group, as seen in Figs. 1,' and;I 5,' and, from their function, ma be termed lift pins, eing secured at its lpin 14 of the-left group of lower end to the y ft-rod 23 being'secured to feed-links", and a the pin 14 of lthe right group of feed-links.-

24 is a stop-latch, pivoted Iat 55 between ,the drill-frame chords 9, Fig-"5, and adapted, by gravity, to normally present its edge in the path of the thrust-bearing 17' of; the air of left drill-'spindles 15, as seen dlearly'int ig.

One or more drills may 44be, used, and they can be arrano'ed in any manner desired, that is, if one dri l is used, it may used, they may be placed all on one side, or

sidef Similar y, any suitable power mech- -anis`m`may be used to transmit rotary motion to any of the parts. I do not, therefore, confine myself, in any of these res ects, to the precise devices herein illustrated? Having thus described my invention, vwhat I claim as newAv and desire to secure by Letters Patent is,

1. In a railroad track-rail' drilling-machine, the combination of oppositely disposed drills,

means for rotating the drills, and feeding and retracting,.mechanism including a pair of alining each pair of links to resenta rigid thrust connection with the dri ls, and flexing them to retract the drills, and a single lever connected at one end with each pair of links to im )ose a pressure upon them when alined rust connection, to"feed the drills.
